I stand by they need more capacity, BUT the one thing I will say is that comparing previous to now misses other important things. Kitchen equipment has shrunk, and techniques could have made things quicker. Along with dumbing down the menu (for lack of a better term). For example, if previously they hand-made their sandwiches, but now moved that process off site and now they are all premade, that would make things go MUCH faster despite losing a dining space. Basically, dropping quality helps them need less kitchen space. I wouldn't be shocked at all if you told me they added tables and made things more compact in existing spaces either.
Now, again, I do think more is needed. We've had numerous discussions about the lack of seating to eat and the lines (which doesn't include how awful things are at MK), but I do think more than just the number that were there vs now there doesn't entirely tell the story.
